After some more debugging (trying applications one by one) I found the culprit: pidgin
ksmserver works fine until I launch pidgin, then it gets stuck, with the symptoms described above.
Running "/usr/bin/env -u SESSION_MANAGER pidgin" instead of "pidgin" works fine and does not create problems in the system.
